Table 49 Execute Device Diagnostic Command (90h)

The Execute Device Diagnostic command performs the internal diagnostic tests implemented by the

device. The results of the test are stored in the Error Register.

The normal Error Register bit definitions do not apply to this command. Instead, the register contains a

diagnostic code. See “Table 31 Diagnostic Codes” on Page 47 for the definition.
